Hand model processing in the mold, industrial production products required by a variety of molds and tools. Generally speaking, it is a tool used to make shaped articles. This tool is composed of various parts. Under the action of external force, the blank becomes a tool with specific shape and size. Different molds are made up of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material. Known as the "mother of industry". Any commodity is made by mould. It can be said that there is no production without mould. It is widely used in various industries
For example: our common TV and other household appliances, mobile phones, telephone shell and other communication equipment products are produced by injecting plastic heating software into the mold to cool and form, and the electric cooker is also made of metal plate pressed into such a shape by the mold. The mold has a specific contour or cavity shape. The mold is a tool with complex shape. It bears the expanding force of the blank and has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
The cost of solid mold manufacturing is generally very high, a set of large-scale manual mold processing is tens of thousands or even millions, especially in the medical industry, millions of molds are very common. If there is unreasonable structure or other problems in the process of installing the mold, the loss will be great. So generally, first confirm the appearance, structure and function with the hand board, and then open the mold for mass production after confirming that there is no problem.
In the process of hand-made model processing, the model can also be called sample, sample piece and template. In some places, it is also called "first board", that is, the first template of the product. In Japan, it is also called "hand-made". The English translation is "rapid prototype". Hand board is a step to verify the feasibility of the product. It is a direct and effective way to find out the defects, deficiencies and drawbacks of the design product, so as to improve the defects. Until the deficiencies can not be found from individual hand board models, it is usually necessary to carry out small batch trial production, and then find out the deficiencies in the batch to improve.
Usually, a hand-made model processing product just developed or designed needs to make a hand-made model. Generally, the designed product can not be perfect or even can not be used. Once there are defects in direct production, it will be scrapped, which greatly wastes manpower, material resources and time. In general, there are a few samples of hand boards, which have short production cycle and less manpower and material resources. We can quickly find out the shortcomings of product design and improve them, so as to provide sufficient basis for product finalization and mass production.
